[FreeNX-kNX] cant get working remote printing

Tue Jul 24 22:00:09 UTC 2012

Chris, about the password, i forget to change the second place.

I found that in nxsmb script variable NXSAMBA_PORT="$PORT" is resolving to
a wrong port. In my case, in nxsmb is resolving to 13004, but in terminal
environment i have  NXSAMBA_PORT=5004. I force that port in nxsmb, and it
worked.

Now, that wrong port is sent by nx client, right? how can i correct this.
thanks, Eric
